Ajax error on IIS7

Question

Hi,

I am facing very unusual issue. Previously our application was running on IIS 6 but now we swithed ti IIS 7. Now on IIS 7, we get following error where ever we redirect to another page using Response.Reditect(url).

Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near' '!DOCTYPE html P'.

Can anyone help how can we fix the issue. We want least number of changes to be made in the code.
